Abstract

A digital subscriber line 'XDSL' communication system for optimizing dynamic range in digital multi-tone modulated (DMT) modems. The system comprises a digital subscriber line access multiplexer (DSLAM) and at least one modem. The DSLAM distributes a near end crosstalk (NEXT) model of anticipated disturbance from neighboring disturber subscriber lines. The at least one modem has shared and discrete components forming a transmit path and a receive path. The at least one modem couples to the DSLAM and is responsive to the distributed NEXT model there from to adjust a dynamic range of an analog portion of the receive path to accommodate the anticipated disturbance modeled in the distributed NEXT model.
